The HOTHREAT initiative strategically addresses the vulnerability of hotels and conference centers to CBRNe (Chemical, Biological, Radiological, Nuclear, and explosive) terrorist threats. This project unites a consortium of 19 partners from 8 EU Member States, including a mix of private and public stakeholders, experts, security firms, and law enforcement, to fortify the security framework of the EU’s hospitality sector. Its primary aim is to enhance societal safety by conducting detailed vulnerability assessments, identifying best practices, and formulating customized CBRNe protection strategies.
